Hello all,

I am trying to create a @External annotation in the Ecore model:

<eStructuralFeatures xsi:type="ecore:EReference" name="relatedItem" upperBound="-1"
        eType="ecore:EClass platform:/plugin/org.eclipse.emf.ecore/model/Ecore.ecore#//EClass">
      <eAnnotations source="http://www.vsd-project.org/vsee/annotation/technical">
        <details key="meta-type" value="vsee.eClass().ePackage.getEClassifier('EngineeringDataItem').oclAsType(ecore::EClass).isSuperTypeOf(self)"/>
      </eAnnotations>
      [B]<eAnnotations source="teneo.jpa">
        <details key="value" value="@External(type=&quot;org.eclipse.emf.teneo.hibernate.mapping.EcoreModelElementType&quot;)"/>
      </eAnnotations>[/B]
    </eStructuralFeatures>

But I have the following error:

org.hibernate.MappingException: Unable to instantiate custom type: org.eclipse.emf.teneo.hibernate.mapping.EcoreModelElementType
	at org.hibernate.type.TypeFactory.custom(TypeFactory.java:187)

	... 20 more

I'm trying to do what it says on the following lines:
Note that instead of using the Type annotation one can probably (==not-yet-tested) also use the External annotation (see section above) with the type attribute set to: org.eclipse.emf.teneo.hibernate.mapping.EcoreModelElementTyp e

Am I doing something wrong? It is correct to use a jpa annotation for this?

Thanks in advance.

Best Regards,

Fernando

Hello,

A little more information to my previous post.

I am trying another method using persistence.xml file:

<?xml version="1.0" encoding="utf-8"?>
<persistence-mapping xmlns="http://www.eclipse.org/emft/teneo"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">

			</property>
			<property name="validItem">
				<type type="org.eclipse.emf.teneo.hibernate.mapping.EcoreModelElementType"/>
			</property>
		</eclass>

	</epackage>

</persistence-mapping>

Fragment of the ecore:

Hi Fernando,
Yes this was a bug. I solved it and published a new build. Let me know if this one still gives you troubles.

Hi Fernando,
I think that this error occurs because EMF tries to save the eclass and assumes that the eclass must be in a resource
to. This error seems to be thrown before the hibernate save occurs. Let me know if the latest build still has this error.

Dear Martin,

Thank you very much for your reply. With the new build (1.2.0.v201102272039) work perfectly (adding the @External annotations in Ecore file)! Smile

But I have tried to add the annotations from the persistence-mapping.xml file and does not work. Please, see below my persistence file:

<?xml version="1.0" encoding="utf-8"?>
<persistence-mapping xmlns="http://www.eclipse.org/emft/teneo"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">

	<epackage namespace-uri="http://www.vsd-project.org/vsd/ir5">

		<eclass name="EngineeringDataCategory">
			<property name="relatedItem">
				<type type="org.eclipse.emf.teneo.hibernate.mapping.EcoreModelElementType"/>
			</property>
			<property name="validItem">
				<type type="org.eclipse.emf.teneo.hibernate.mapping.EcoreModelElementType"/>
			</property>
		</eclass>

	</epackage>

</persistence-mapping>

The file is read correctly, but then does nothing. Both properties (relatedItem and validItem) are list. What do you think?

Best Regards,

Fernando

Hi Fernando,
Hmm, and if you try something like this:
<property name="relatedItem">
<external> org.eclipse.emf.teneo.hibernate.mapping.EcoreModelElementTyp e </external>
</property>
